Re: Is it recommended to tighten ra/dec clutches during mount transportation?
Rolando,
I wonder ... leaving the clutches fully tightened may
not affect “the clutches” themselves, but since they are tightened down onto the
fully meshed worm, I would think that any severe bump on the mount will transmit
some the toque to the worm gear bearings, and worm tooth, before they slip.
However, clutches are well designed to slip with an OTA crashing into the pier,
so there is always some assurance that the problem won’t happen.
I would favour a “slightly” loosened clutch, to
let the axle “slip” (more easily than in an emergency), if it needs to during a
vehicle or airline cargo bounce.’container Leaving it completely loose would
cause awkward handling when the user picks it up before retightening clutches
during setup, and equally so during take-down. Besides, you normally need to
loosen clutches for a comfortable resting position, after packing the mount into
its transport container anyway. Retightening them again for the trip serves no
purpose. Might even explain why some may have been damaged during carrier
delivery.
Not a big deal, but somewhat looser clutches can do no
harm.

Hello group,
As I'm getting ready for first light test of the new Mach1, I wonder if there are any safety recommendations for transporting the case to remote site, i.e. is recommended to tighten the clutches on RA/DEC or leave them loose or doesn't matter to avoid mechanical damage. If I recall correctly, I've received the original box from AP with all clutches tightened, but I'm not sure if that's done on purpose.

Re: 41P/Tuttle-Giacobini-Kresak orbital tracking behaviour
There was no :NS# code in my ASCOM logs. A keypad press can also do this without being logged. But as I said, after looking at the code the only way that the declination would be made negative is by changing side-of-pier. Anyway, I will give another try on tuesday night if weather permits with "Calibrate move directions on first slew" enabled. You should do that, but I don't think that will help this problem. -Ray Gralak Author of APCC (Astro-Physics Command Center): http://www.astro-physics.com/index.htm?products/accessories/software/apcc/apccAuthor of PEMPro: http://www.ccdware.comAuthor of Astro-Physics V2 ASCOM Driver: http://www.gralak.com/apdriverAuthor of PulseGuide: http://www.pulseguide.comAuthor of Sigma: http://www.gralak.com/sigma-----Original Message----- From: ap-gto@...

Thanks Ray for your input,
Hi Yves,
The ":NS#" command swaps N/S directions. The driver normalizes the direction when that option is selected so that Dec autoguider moves are always normalized based on pier side.
There was no :NS# code in my ASCOM logs.
Hi Yves,
The ":NS#" command swaps N/S directions. The driver normalizes the direction when that option is selected so that Dec autoguider moves are always normalized based on pier side.
However, I just checked the code and the *only* way the driver changes DeclinationRate sign is if their has been a pier flip. So, are you sure that in 6 hours of time (9:10 pm to 3.07 am) that there could not have been a pier flip?
There was no pier flip during that period. The comet crossed the meridian at 04:12 local time.
BTW, by ASCOM (and A-P) definition, a pier flip includes any scope movement where the scope's Dec axis moves through Dec=90 (or Dec=-90). Their doesn't have to be a physical pier flip, but one usually will happen if the same object is being targeted.
My mount was always around DEC=+57*46:51(comet 041p) except for autofocus star that was on the same side of meridian.
If you are sure there wasn't a pier flip, then it had to be ACP sending an inverted rate.
I really don't know what could be the problem. Three weeks ago I had the same problem and three days ago the problem only occured at the beginning of my imaging run but disappeared during the same night.
Anyway, I will give another try on tuesday night if weather permits with "Calibrate move directions on first slew" enabled.
I will let you know about my results.

Ray,
Ok concerning the ASCOM option.
Here are two sections of ASCOM logs already reported earlier.
028684 2017-04-13 21:10:17.448: ASCOM: Info : SET DeclinationRate = -0.044520572702055 028685 2017-04-13 21:10:17.466: Driver: Info : CommandBool TX=':RD- 0.00296#'

In the first log section,The SET DeclinationRate has a negative value like the CommandBool TX=':RD-0.00296#' BUT this was causing bad tracking. In the second log section The SET DeclinationRate has a negative value as opposite to the CommandBool TX=':RD-0.00298#' who has positive value. However
the comet tracking was ok.
According to the logs, does the :RDxxxx# value should always be multiplying the SET DeclinationRate by -1? Does these values are related to each other?
What is the internal DEC direction protocol command that would cause my problem? Thanks a lot!

Hi Ray,
Three days ago, when imaging 41P/Tuttle-Giacobini-Kresak, I've noticed a vertical
nucleus trail even if I was tracking on the comet. I've inspected images
took
3
weeks earlier and saw also a small nucleus trail but at that time I thought
it
was
an
elongated form nucleus but I was wrong. This time, it was more evident
that
the
mount was not tracking the comet as it should.
The weird part is that imaging session began with this behaviour and my
last
imaging session was ok.
I began to suspect APCC tracking correction but seems to have nothing to
do
because tracking correction was enabled during my last imaging tests.
However, in inspecting log files I've noticed something that needs to be
share
to
your attention.
Here are parts of my log files from ACP (DC3-Dreams), ASCOM driver
and
APCC.
Please note the difference in value between the two AP ASCOM log
sections
(AP
ASCOM driver that produce vertical nucleus trail and AP ASCOM driver
WITH
good
comet tracking). One :RDxxxxx# is negative and the other is positive. The problem
seems related to this anomaly.
Ray, I will sent you complete logs and images on request.
ASCOM and APCC updated to their latest version.
HAPPY EASTER!!!

Re: 41P/Tuttle-Giacobini-Kresak orbital tracking behaviour
Hi Yves, The ":NS#" command swaps N/S directions. The driver normalizes the direction when that option is selected so that Dec autoguider moves are always normalized based on pier side. However, I just checked the code and the *only* way the driver changes DeclinationRate sign is if their has been a pier flip. So, are you sure that in 6 hours of time (9:10 pm to 3.07 am) that there could not have been a pier flip? BTW, by ASCOM (and A-P) definition, a pier flip includes any scope movement where the scope's Dec axis moves through Dec=90 (or Dec=-90). Their doesn't have to be a physical pier flip, but one usually will happen if the same object is being targeted. If you are sure there wasn't a pier flip, then it had to be ACP sending an inverted rate. -Ray Gralak Author of APCC (Astro-Physics Command Center): http://www.astro-physics.com/index.htm?products/accessories/software/apcc/apccAuthor of PEMPro: http://www.ccdware.comAuthor of Astro-Physics V2 ASCOM Driver: http://www.gralak.com/apdriverAuthor of PulseGuide: http://www.pulseguide.comAuthor of Sigma: http://www.gralak.com/sigma

Hi Ray,
Three days ago, when imaging 41P/Tuttle-Giacobini-Kresak, I've noticed a vertical
nucleus trail even if I was tracking on the comet. I've inspected images took
3
weeks earlier and saw also a small nucleus trail but at that time I thought it
was
an
elongated form nucleus but I was wrong. This time, it was more evident that the
mount was not tracking the comet as it should.
The weird part is that imaging session began with this behaviour and my
last
imaging session was ok.
I began to suspect APCC tracking correction but seems to have nothing to
do
because tracking correction was enabled during my last imaging tests.
However, in inspecting log files I've noticed something that needs to be
share
to
your attention.
Here are parts of my log files from ACP (DC3-Dreams), ASCOM driver and APCC.
Please note the difference in value between the two AP ASCOM log sections (AP
ASCOM driver that produce vertical nucleus trail and AP ASCOM driver
WITH
good
comet tracking). One :RDxxxxx# is negative and the other is positive. The problem
seems related to this anomaly.
Ray, I will sent you complete logs and images on request.
ASCOM and APCC updated to their latest version.
HAPPY EASTER!!!

The ASCOM Calibrate move directions on first slew (recommend) was disabled. Were you talking about that option?
If yes, how DEC direction could change during the same night if that previous option was still disabled?
